hemodynamics of sexual dysfunction following nerve sparing Radical cystoprostatectomy

Fourteen patients with invasive bladder cancer underwent penile duplex scanning and dynamic infusion cavemosometry preoperatively to assess arterial and venous hemodynamics. Nine of these patients were impotent after nerve sparing Radical cystoprostatectomy and had repeated duplex scanning and cavemosornetry six months postoperatively. On penile duplex all 9 patients had arterial insufficiency on at least one side in-spite of individual vesical arteries ligation. On dynamic cavernosometry. 2 patients had the criteria suggestive of corporoveno-occlusive dysfunction. We concluded that impotence following nerve sparing radical cystoprostatectomy is predominantly arterial in nature. The possible causes and points of technique are discussed
